Okay it's soved! Thank's

any solution ?

aha i understand the process!
so what i need is to remove controls recently added dynamicaly to wpf window,
i need something like ..Children.Remove(?);
it's not logical to use visibility .. hidden

It's easy, think a little bit more:
if (dataGridView1 [i, j].Value.ToString()==comboBox1.Text)
{
dataGridView1[i, j].Style.BackColor =Color.Yellow;
/* OR you can use to Highlight all the row : dataGridView1.Rows [j].DefaultCellStyle.BackColor = Color.Yellow; */
}
Else dataGridView1[i, j].Style.BackColor =Color.White;//clears the selection

Welcome!!
:)

Welcome!
You can add before using the code :

If(dataGridView1 [i, j].Value!=null)
{
//here the previous code here
}

This exception is throw because there is some cells not containing a value, so you cannot parse a null value to .toString().

If the solution is done, put your question as solved :-) gdluck

welcome!
put your answer as solved if it is done.

Welcome!
It seems I need big time to get involved in this issue..
Summer will be enough....

Thank you!

okey, i'll search.
thank's for help an advices.

but i'm trying to get more skills, or maybe learn something how it works in binaries ...
i also wish to know how to get the bytes[] of a function:
if i wrote a function in c#, how can i get it bytecode, also execute it. maybe similar to the Object byte conversion...
(how the computer or machine read it codes low level, not affected by C# language)
are these steps dangerous or not appreciated ?
is there any book or step to learn ? i didn't find a right book on the internet

hehe :)
don't you have any idea :S ?

by the way i asked a question before, but no one gave me a solution, if you have any idea:

i need a funtion that executes bytecode :
if i load byte[] b of an executable (byte[] b = File.ReadAllBytes(string path))
how can i execute the executable using the byte[] b
//i don't want to use Process.Start ...
//i need to execute an executable by a byte[] variable

Aha it's ok, i missed to add it !
it works only with ToByteArrayBetter.
other method still throwing same exception.
anw thank you, i think this method is working fine with me :)

Thank for help,
(my namespace is "Test",contains class "Client")
i have some trouble (Exceptions thrown), i did :

Client Cl = new Client("John");
byte[] b = ToByteArrayBetter(Cl);

when i used ToByteArrayBetter :
Type 'Test.Client' in Assembly 'Test, Version=1.0.0.0, Culture=neutral, PublicKeyToken=null' is not marked as serializable.

even when i used ToByteArraySimple :

Type 'Test.Client' cannot be marshaled as an unmanaged structure; no meaningful size or offset can be computed.

how can i handle ?

i need something like :

byte[] CL = ConvertFrom(CLI);//ConvertFrom a written method to convert Object CLI to a byte...

let assume i added a little executable to my project resources as file (i removed extension .exe to hide it type)

* if i want to execute with output environnement :
(make it a file by writing it bytes in a filepath exemple "prog.exe"
using : byte [] b=global::namespace.properties.resources.prog; and system.io ...to make it.....etc...
finally calling system.diagnostics.process to start execution..

* if i want to execute the prog without this hole process, by only having the bytes byte[] as parameter, and start the execution on this set of bytes, without creating an associated file ... how can i ?

the o.s surely executes an executable by loading its bytes bytecode an run it, how to do that in c# ?

thanks.
